Don't worry, many people misspell display that way. The word display is easy to be mistaken while typing.
A visual display unit, often called simply a monitor or display, is a piece of electrical equipment which displays images generated from the videooutput of devices such as computers, without producing a permanent record. Most newer monitors typically consist of a TFT LCD, with older monitors based around a cathode ray tube (CRT). The monitor comprises the display device, simple circuitry to generate and format a picture from video sent by the signals source, and usually an enclosure. Within the signal source, either as an integral section or a modular component, there is a display adapterto generate video in a format compatible with the monitor.
CRT
Pros:
- Very high contrast ratio (20,000:1 or greater, much higher than many modern LCDs and plasma displays.)
- High speed response
- Excellent Additive color, wide gamut and low black level limited only by external environment.
- Can display natively in almost any resolution and refresh rate
- Near zero color, saturation, contrast or brightness distortion. Excellent viewing angle.
- No input lag
- A reliable, proven display technology.
Cons:
- Large size and weight (a 40" unit weighs over 200lbs)
- Geometric distortion in non-flat CRTs
- Older CRTs are prone to burn-in.
- Warm up time required prior to peak luminance and proper color rendering.
- Greater power consumption than similarly sized displays, such as LCD.
- Screened devices are prone to moire effect at highest resolution (does not apply to triple-tube projection)
- Intolerant of damp conditions, with dangerous wet failure characteristics.
- Small risk of implosion (due to internal vacuum) if the picture tube is broken in aging sets.
- Use under Lower refresh rates causes noticeable flicker
- Internal lethally high voltages
- Flyback transformer produces characteristic high-pitched noise when close to set.
- Increasingly difficult to obtain models at HDTV resolutions, due to consumers' perception of antiquity.
Pros:
- Very compact and light
- Low power consumption
- No geometric distortion
- Rugged
- Little or no flicker depending on backlight
Cons:
- Low contrast ratio.
- Limited viewing angle. This causes color, saturation, contrast and brightness to vary, even within the intended viewing angle from mere variations in posture.
- Uneven backlighting in some monitors can cause brightness distortion, especially toward the edges.
- Slow response times, which cause smearing and ghosting artifacts (although many modern LCDs have response times of 8ms or less).
- Only has one native resolution. Displaying other resolutions requires a video scaler, which degrades image quality at lower resolutions.
- Fixed bit depth, many cheaper LCDs are incapable of truecolor.
- Input lag
- Somewhat more expensive than CRT
- Dead pixels are possible during manufacturing
Main article: Plasma display
Pros:
- Compact and light
- High contrast ratios (10,000:1 or greater)
- High speed response
- Excellent color, wide gamut and low black level.
- Near zero color, saturation, contrast or brightness distortion. Excellent viewing angle.
- No geometric distortion
- Highly scalable, with less weight gain per increase in size (from less than 30 inches wide to the world's largest at 150 inches).
Cons:
- Large pixel pitch means either low resolution or a large screen
- Noticeable flicker when viewed at close range
- High operating temperature
- Somewhat more expensive than LCD
- High power consumption
- Only has one native resolution. Displaying other resolutions requires a video scaler, which degrades image quality at lower resolutions.
- Fixed bit depth
- Input lag
- Older PDPs are prone to burn-in
- Dead pixels are possible during manufacturing
[edit]Penetron
Pros:
- See-through for transparent HUDs (although LCDs are also transparent, they are not self-lighting.)
- Very high contrast ratios.
- Extremely sharp.
Cons:
- Color displays are limited to about four tints.
- Orders of magnitude more expensive than the other display technologies listed here.
